I converted my mysql field value to kv using kv filter...

filter{  
kv{  
field\_split =\> "&?"  
}  
}  
but when i saw the result....it was in key and value form only...but in string codes...means my line break to kv form but in showing string...

So I am not able to call individual key and value....bcz its again become string...

Is there is any solution...after break string to kv form ....it index in kv form only..not a string..

Actually I want to send json after logstash fetch data from mysql in this form...  
{  
"group" : "fans",  
"user" : [  
{  
"first" : "John",  
"last" : "Smith"  
},  
{  
"first" : "Alice",  
"last" : "White"  
}  
]  
}

But logstash makes each field of the mysql in seperate key valye form...  
and then sending to elasticsearch..  
But before send to elasticsearch I want to make my data in the above code way...Is there any possible way...
